SCS 4000/5000 Series™ Installation & Operation Manual
11.
Hold the Manual Override switch in the INC position until pressure reaches maximum. This ensures that the
motorized Control Valve is fully open. Verify maximum pressure and RATE. (Pressure gauge is not
supplied).
Note:
A pressure gauge must be installed to properly monitor the system.
12.
Adjust agitator line hand valve for desired agitation. Verify the maximum pressure is still present.
13.
Hold the Manual Override switch in the DEC position until pressure is at its minimum. This ensures that the
motorized Control Valve is fully closed. Verify minimum pressure and RATE. If minimum pressure and RATE
cannot be obtained, consider using the by-pass plumbing system in Chapter 12,
.
Field Test
1.
Drive at the target application speed with booms off to verify the SCS console speed display.
2.
Turn the booms ON and place the console in AUTO mode. Increase or decrease vehicle speed by one MPH
[2 km/h]. The system should automatically correct to the target application rate.
3.
If for any reason, the system is unable to correct to the desired RATE, check for an empty tank, plugged
line, malfunctioning pump, improper vehicle speed, or a defect in the system.
4.
If the system still does not appear to be correcting properly, review the Initial System Set-up. For additional
troubleshooting tips, refer to Chapter 9,
5.
At the end of each row, toggle the master switch OFF to shut off flow. This will also shut off the area
totalizer.
6.
Verify the area covered and volume used.
Preventive Maintenance
Preventive maintenance is most important to assure long life of the system. The following maintenance
procedures should be followed on a regular basis:
1.
Flush entire system with water after use of suspension type chemicals. Failure to clean system can result in
crystallization of chemicals which may plug the flow meter, lines, and/or tips.
2.
Flush and drain tanks before storing the vehicle.
Note:
Freezing temperatures may damage the flow meter if the system is not properly drained.
3.
Disconnect the flow meter at the end of each spraying season and clean the turbine and inlet hub. Clean off
all metal filings and wettable powders which have hardened on the plastic and metal parts. Check the inlet
hub and turbine assembly for worn or damaged turbine blades and bearings. Flush with clean water and
drain.
4.
Remove the SCS console when not in use for extended periods and store the unit in a dry, temperature
controlled environment. Keep the SCS console from freezing and away from moisture.
